"Oh, right, Aulisel. Before I entered that mysterious space, a green curtain of light blocked my way."
"It was probably a defensive measure left behind by whoever built that mysterious space."
"It called itself the Ghost Gate, opened once every three thousand years, and only allowed creatures from Earth to enter. All three conditions had to be met."
"And this Ghost Gate connected to many unknown spaces or worlds."
"My guess is that this mysterious space, including whoever built this Ghost Gate, was very likely a remnant of a civilization from an epoch before ours."
"And two years ago, the Abyss Devils happened to meet the conditions for opening the Ghost Gate. Their entire race entered it and went to other spaces or worlds."
Jiang Yang laid out all his conjectures to Aulisel.
Aulisel nodded, then looked at the enormous stone gate before her-or rather, the Ghost Gate-and asked,
"Jiang Yang, how long can this Ghost Gate remain here?"
"I've already broken the central control system of that mysterious space. Naturally, this Ghost Gate is under my control now. It can stay as long as I want."
Jiang Yang gave a faint smile and spoke confidently.
"Can we enter that mysterious space through this 'Ghost Gate' too?"
Aulisel continued with a smile. Her hands rested quietly behind her back, but interest also showed in her eyes.
Unknown civilizations, unknown technology, and unknown, mysterious knowledge always excited her.
"Of course, but I'll have to make a slight adjustment so our people don't end up like those Abyss Devils, transported to some unknown space."
Jiang Yang laughed and pointed at the Ghost Gate. A ray of golden light entered it, instantly sealing the space-time threads within and leaving only the thread connecting that mysterious space to this Ghost Gate.
"All done, Aulisel.
